Control of structure borne noise in the scaled demonstrator using actuators parallel to the structure

Based on previous experiments developed un simple systems a structure borne noise active control has been implemented. The main principles of the control system are:- Piezo actuators parallel to the main plane of the structure in order to introduce moments.- Acceleration Feedback Control.- Active modal damping with second order filters.

The system is potentially applicable in large, rigid system in with a great percentage of free contours.
